It used to tick me off how for every update the progress bar would reach 99%, and then stay that way for about a week before release.
Now it annoys me that they announce that the update's done save for one bit of animation that hasn't been turned in, but the progress bar's been at 97 for a week with 5 tasks to go.
Like, it's not outrage or anger of any kind, I just resign myself to wait it out like most people. It's just the fact that they have a fancy progress bar to show transparency but its purpose becomes useless when every update reaches its end, that annoys something deep in my personal idiosyncrasies.
